Manchester United have been linked with an exciting double swoop on Marseille.
Both are key parts of Marcelo Bielsa's team which have ascended to the top of Ligue 1, ahead of PSG.
Imbula is a player long linked with the Premier League, a central midfielder compared to Patrick Vieira, he is only 22 and beginning to fulfil his potential.
He has been heavily linked with a move to Chelsea and Arsenal previously, and is thought to be valued at around £25 million.
An ever present this season, he averages almost two tackles per game and has a pass completion rate of 89 per cent.
Defender Bruno N'Koulou is another intriguing addition, playing a key role at centre-back for the club, leading the team in interceptions averaging 3.3 per game.
Marseille would certainly be reluctant to lose the duo mid-season, especially with an unexpected title challenge looking possible.
Coach Bielsa was angry with the club's disappointing summer transfer business, and he will be resistant to losing two key players mid-season, who have each started all 11 Ligue 1 games.
It is this which causes the biggest difficulty for United, but a £40 million package for the duo will prove tempting, if the Red Devils view them as more achievable signatures than Kevin Strootman and Mats Hummels.
